[Yaesu] Deaf FT-901DM

Hi Folks;

I picked up an FT-901DM recently that's got a deaf receiver. I've  
checked the antenna fuse and it's good. Also checked the first RF amp  
transistor by plugging it into a Kenwood radio, where it worked fine.  
I've re-seated the plug in boards and done a little other basic poking  
around. Getting 50 Watts out from the transmitter with an old pair of  
6146's.

The calibrator level is about S-7 on 20m, and the preselector does  
peak the calibrator in a normal way. However, when I connect a dummy  
load to the antenna connector, the calibrator level drops down to an  
S-1. Is this normal behavior??
